IMPROVEMENT IN sTRAw AN-D cos ELEVATORS.

Specification forming part of Letters Patent No. 1 76,9 I 6, dated May 2, 1876; application filed March 29, 1875.

Be it known that I, :JOIHN Q. ADAMS, of

Marseilles, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Elevators for Corn- Oobs, Straw, Grain, 86C. and I do hereby declare the following to be-a full and exact descriptionv of the same, reference being hadto the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of my improved elevator, partly broken away to show the arrangement of the gearing; and Fig. 2 is a transverse vertical section through the gearing and base of the elevator-frame.

Similar letters of reference in the accompanying drawings denote the same parts.

My invention has for its object to provide an improved elevator for general purposes, such as the stacking of corn-cobs, theele vation of grain, hay, straw, &c., which can be adjusted vertically and horizontally upon its supporting-frame and driving mechanism without interfering with or discontinuing its operation. v

My invention consists in certain details of construction in an elevator, more fully set forth and particularly claimed herein.

In the accompanying drawings, A is the base-frame, composed of strong timbers, and B is the horizontal inclosing-case mounted thereon to receive the large crown-wheel G. The case is composed of two parts, the lower one being bolted to the timbers, and provided with a short vertical shaft, D, in the center, upon which the crown-wheel is mounted. The upper half of the case is centered upon this shaft, so as to turn freely, and is guided bythe side flanges composing the edges of the case. E are angular guides secured to the base-timbers, and extending over the top of the case to hold the two parts thereof in po-" sition, as shown in Fig.1. The two parts thus united completely inclose the cr'o wn-wheel, and effectually exclude the dirt therefrom when the machine is in operation. The crown-wheel is made double, the teeth upon its under side engaging with a beveled pinion, F, projecting through the lower part of the case at one edge, and mounted upon a horizontal shaft, G, in the side of the frame, and the teeth upon such upper part of the case, as shown.

its upper side engaging with a large beveled pinion, H, projecting through the upper part of the case at one edge, and mounted upon a horizontalv shaft, I, having its bearings upon The shaft G has its bearings in the brackets or hangers J J, depending from the lower half of the inelosing-case, as shown in 2, and is'pro'vided with a pulley, K, by which the power is applied to drive the gearing. A case, L,,seeured to one of the base-timbers beneath the case incloses the pinion F, and serves as a shield to exclude dirt and other foreign substances therefro1n.. One of bearings of the shaft I is formed of an upright, M, upon the top of the case near one edge, and the other is formed in the inner side of a box, N, se-

cured by suitable means to the opposite edge of the top, so as to receive the pinion H. This case is also provided with a hinged cover, secured in place by proper catches, to protect the pinion from dirt or other matter that might otherwise fall upon it, and at the same time hold the pinion in mesh. The eye of the double crown-wheel is surrounded upon the under side with a large wide boss, 0, which furnishes bearing for such wheel, and holds its teeth out of contact with the lower half of the case. The crown-wheel does not depend upon the hub for holding it steady 5 but the space between the ends of the cogs and either the upper or under side of the case is designed to be so made that if the wheel springs off the pinion F the case will act as a slide at any point to hold it in gear. P is a long elevatorframe,'formed of one or more sections. The lower end is mounted upon the shaft I by means of side brackets Q, so as to turn freely, and its outer end is provided with pivoted legs B, by which it is supported upon the ground. S S are endless carryingbelts, connected by cross-bars, and extending around flanged rollers TT upon the shaft I, and correspondin g rollers U U upon a shaft, V, mounted in brackets or hangers W at the outer end of the "elevator-frame. These belts and crossbars constitute the elevator in connection with the side pieces and the bottom of the frame, the crossbars sweeping over such bottom in the ordinary manner. The lower end of the elevator-frame is provided with a curved metallic liopper, X, which receives,thesubstancej;

to be elevated, andi'eeds it to the rcarrying belts and bottom of the frame.

-When the machine is to be operated the elevator is first fixed at the proper inclination by turning it upon the shaft I and adjusting the position of the pivoted-legs. ;-;Power.=is:- then applied to the pulley K, to operate the pinion F and drivethe croWn-wheel,,. ,v5{ithin the inclosing-case, the crown-wheel, in its turn, driving the pinion H upon the shaft I, and thus operating the carrying-belts. to elevatethe material fed upo'n:them,--aswill-be readily understood.
